The House district includes parts of Montour and Northumberland counties in central Pennsylvania.
Democrats currently hold a one-seat state House majority, although the open Schlegel Culver seat means the effective margin is temporarily 102-100.
Rep. Mike Zabel, a Democrat from Delaware County accused of sexual harassment, said last week he's not quitting but did not vote on legislation Tuesday.
The Republican majority in the Senate is 28-22.
